Farm Grazing Levels, Department Of Agriculture, Western Australia Jan 1972

Farm Grazing Levels, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

Stocking rates in many dairying areas are so low that the Division has established nine grazing level demonstrations in various areas.

Their aim is to demonstrate that higher stocking rates are practical on existing farms.


Dairy Beef Shows Healthy Profits, D J. Barker Jan 1971

Dairy Beef Shows Healthy Profits, D J. Barker

Journal of the Department of Agriculture, Western Australia, Series 4

The October, 1970, issue of the Journal of Agriculture included results from the first year of a dairy beef production trial at Bramley Research Station.

Three Beef Raising Systems For Butterfat Producing Properties, Department Of Agriculture, Western Australia Jan 1970

Three Beef Raising Systems For Butterfat Producing Properties, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

THREE-QUARTERS of the calves born in autumn on butterfat farms are not required as milking replacements and are thus available for beef production or immediate sale, at about $20 a head.

The profit from selling beef must be compared with that from selling excess calves off their mothers.

Such a comparison is being made by Department of Agriculture Beef Research Officer D. J. Barker in a series of trials at Bramley Research Station, Margaret River.


High Stocking Rate On Kikuyu Dairy Pasture : Progress Report On Grazing Trials On Kikuyu-Sub. Clover Pasture At Denmark Research Station, F E. Ryan Jan 1969

High Stocking Rate On Kikuyu Dairy Pasture : Progress Report On Grazing Trials On Kikuyu-Sub. Clover Pasture At Denmark Research Station, F E. Ryan

Journal of the Department of Agriculture, Western Australia, Series 4

KIKUYU is one of the most valuable pasture plants on dairy farms in the South-West of Western Australia.

It combines well with subterranean clover and ryegrass if heavily stocked, and pastures managed in this way can be cut for legume-grass hay in the spring. However, relatively little is known of its carrying capacity or potential for production under grazing.


More Butterfat Per Acre At Denmark Research Station, Department Of Agriculture, Western Australia Jan 1969

More Butterfat Per Acre At Denmark Research Station, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

STOCKING rates on dairy farms are generally too low and can be substantially increased, but unfortunately there is no satisfactory measurement to indicate the potential of a particular pasture or environment.

A trial carried out on Denmark Research Station in 1966-67, to obtain information on carrying capacity of a dryland kikuyu-subterranean clover pasture.


W.A. Dairying : Progress In 42 Years, Maurice C. Cullity Jan 1968

W.A. Dairying : Progress In 42 Years, Maurice C. Cullity

Journal of the Department of Agriculture, Western Australia, Series 4

From hardship and elementary standards, West Australian dairying has developed into a consolidated industry with larger herds, increased output and high quality production.

The changes he has seen are reviewed by Mr. M. Cullity who retired last month from the position of Chief of the Division of Dairying, after 42 years of service to the industry.

THE history of Western Australia's dairying industry has been a story of struggle against hardship, marketing problems and adverse criticism.

In spite of this the industry has steadily grown and greatly improved its efficiency.


Feeding Urea To Dairy Cows, R A. Bettenay Jan 1967

Feeding Urea To Dairy Cows, R A. Bettenay

Journal of the Department of Agriculture, Western Australia, Series 4

IT has been known for some years that the ruminant animal, through the agency of microflora in the rumen, has the ability to use urea as a source of nitrogen, and to convert some of this to protein.


Meadow Hay For The Dairy Herd, F E. Ryan Jan 1966

Meadow Hay For The Dairy Herd, F E. Ryan

Journal of the Department of Agriculture, Western Australia, Series 4

CONSERVATION is the basis of progress in dairy farming and the major form is meadow hay, but unfortunately relatively few dairy farmers give enough attention to the quality and quantity of this important feed.


Good Management For The Springers Pays Dividends, J Y. Langdon Jan 1966

Good Management For The Springers Pays Dividends, J Y. Langdon

Journal of the Department of Agriculture, Western Australia, Series 4

This article gives a striking example of the advantages of calving cows in good and rising condition—and explains why condition around calving time is so important.

ALTHOUGH most farmers know that cows calving in good and improving condition will give higher yields than those calving in poor condition, few use this knowledge to improve the production from their cows.


Dairy Farming In The Busselton-Margaret River District. Part 3. Fodder Conservation, R A. Bettenay Jan 1965

Dairy Farming In The Busselton-Margaret River District. Part 3. Fodder Conservation, R A. Bettenay

Cobalt : Its Use To Control Wasting Disease, Laurence C. Snook Jan 1962

Cobalt : Its Use To Control Wasting Disease, Laurence C. Snook

Journal of the Department of Agriculture, Western Australia, Series 4

FOR many years it was assumed that in Western Australia cobalt deficient areas were restricted to a coastal fringe which rarely extended more than 20 miles inland.

This has proved a costly false assumption. During recent years cobalt deficiency has been diagnosed over extensive areas of inland country.


Some Factors Affecting The Composition Of Milk, K Needham Jan 1962

Some Factors Affecting The Composition Of Milk, K Needham

Journal of the Department of Agriculture, Western Australia, Series 4

FOR many years it has been known all over the world that the composition of milk varies. This variation in quality is considered as a serious problem wherever the dairy industry is established.


A Simple Feeding Guide : Balanced Rations For Dairy Cows, K Needham Jan 1962

A Simple Feeding Guide : Balanced Rations For Dairy Cows, K Needham

Journal of the Department of Agriculture, Western Australia, Series 4

MANY technical articles have been written on the nutrition of dairy cattle and the methods employed in compounding a balanced ration have often been explained.

This article aims to present the principles of compounding a balanced ration in a simplified form, and suggests rations which should be easily adopted on any dairy farm.


Rearing Healthy Calves, Department Of Agriculture, Western Australia Jan 1962

Rearing Healthy Calves, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

NOW is the time to consider some form of grazing management and supplementary feeding for early born calves, especially in the butterfat zone.

The calves are now two to three months old and beginning to forage for themselves, This can be a critical period in their development.

Meadow Hay, Department Of Agriculture, Western Australia Jan 1962

Meadow Hay, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

rriHE nutritive value of pasture is high in early spring and remains so until early flowering.

After this the protein content falls rapidly, the fibre content rises and the plants become more lignifled and their digestibility reduced.


Mineral Supplements, Laurence C. Snook Jan 1962

Mineral Supplements, Laurence C. Snook

Journal of the Department of Agriculture, Western Australia, Series 4

TJRODUCTIVE dairy cows have a high mineral requirement. A deficiency can cause lowered milk production and poor health may result if it is not corrected.

Saving Labour In Feeding Calves, R A. Bettenay Jan 1961

Saving Labour In Feeding Calves, R A. Bettenay

Journal of the Department of Agriculture, Western Australia, Series 4

PRESENT day values are such that no farmer can afford not to dispose of his calves to the best advantage.

With the lighter breeds this might still mean vealing all bull calves within a week of birth, but with heavier breeds it is now more economical to keep all calves until they are at least six to eight months old.


Selecting A Herd Sire, R A. Bettenay Jan 1961

Selecting A Herd Sire, R A. Bettenay

Journal of the Department of Agriculture, Western Australia, Series 4

THERE is now ample evidence that most of the differences in production between herds are determined by feeding and management, with differences in genetic merit playing a relatively minor role.

It seems that the quickest way to increase production is by improved feeding, whilst in some herds much production is being lost by faulty milking techniques.


Hay For The Dairy Herd : Quality Or Quantity?, F E. Ryan Jan 1961

Hay For The Dairy Herd : Quality Or Quantity?, F E. Ryan

Journal of the Department of Agriculture, Western Australia, Series 4

CONSERVATION of hay on dairy farms has increased in recent years but so far emphasis has been on quantity rather than quality and in some districts paddocks are closed up very early to increase yields per acre of hay.

Recent trials have shown that late closing of hay paddocks on dairy farms gives higher quality hay, more winter grazing and a better balanced pasture. The gain in quality more than compensates for any drop in yield.


Cutting Costs In Calf Rearing, N A. Scott Jan 1960

Cutting Costs In Calf Rearing, N A. Scott

Journal of the Department of Agriculture, Western Australia, Series 4

RAISING calves as herd replacements and as a sideline to provide added income is becoming increasingly popular.

This is particularly noticeable since the inception of the Artificial Breeding Scheme whereby farmers are at liberty to breed herd replacements from their most productive cows and use semen from beef breeds for the poorer types.


Foster-Mothering Of Calves, Maurice C. Cullity, K. W. Simes Jan 1960

Foster-Mothering Of Calves, Maurice C. Cullity, K. W. Simes

Journal of the Department of Agriculture, Western Australia, Series 4

"SAVE those calves" is a slogan which has been used frequently in propaganda to reduce the slaughter of heifers when it is thought that the supply of replacement animals to our dairy herds might be unduly low.

Although there is no fear of this at present, the wastage of calves both heifers and bulls, in Western Australia is unduly large.


Can Heifers Be Fed Too Well?, Laurence C. Snook Jan 1960

Can Heifers Be Fed Too Well?, Laurence C. Snook

Journal of the Department of Agriculture, Western Australia, Series 4

DURING recent years, emphasis has been given to the results of experiments conducted overseas, which appear to show that when heifers are generously fed, this reduces their ability to produce milk in later life.

As a result, some dairymen now believe that heifer calves should be kept lean rather than in prime condition.

It has become common to hear statements to the effect that generous feeding encourages calves to become "beefy," at the expense of the milk-producing attributes which are essential in a dairy cow.
